Filter by:This study aims to investigate whether consumers differ in mouthdrying sensitivity and if mouthdrying can be modulated.
Brief Summary: This study aims to investigate whether protein fortification of beverages causes mouthdrying and mucoadhesion and whether this is influenced by saliva flow.
The elderly are weakened by the accumulation of chronic diseases. Their acute decompensation often leads to unscheduled hospitalization, which constitutes a breach of care with often serious consequences in terms of morbidity and mortality. Few studies have identified all the risk factors for unscheduled hospitalization in the very elderly. This project deals with the impact of air pollution on the very elderly as a source of physiological decompensations leading to unscheduled hospitalizations, in association with other individual and environmental risk factors. It complements the Rieho cohort that followed 973 elderly people on the same objective and enriches it with the use of sensors measuring the peri-individual atmospheric environment.
The study is conducted to investigate the effects of priming different cultural orientations on participants' decisions on whether to donate their organs, in an opt-out donation system scenario where the default is a presumed consent on the part of the individual.
Brief Summary: This study aims to investigate whether protein fortification of foods and beverages causes mouthdrying and mucoadhesion and whether this is influenced by age and saliva flow.

The present study aims to investigate the effect of fat level and fat type of a snack on self-reported satiety and associated biomarkers. The relevant individual differences will also be investigated.
The proneness to react to noxious stimuli varies widely between individuals and pain ratings of seemingly identical noxious stimuli may range from "no pain" to "excruciating pain" . Imaging studies in healthy subjects have provided useful information on the identification of the inter-individual variability in pain perception [2,3,4]. These studies have shown that subjective pain reports are closely related to the degree of neuronal activity in several brain regions known to be identified in pain processing. Furthermore, there has been a growing interest in understanding structural and functional mechanisms of inter-individual variability in responses to identical noxious stimuli [5,6,7]. Yet, the relationship between pain perception and various anatomical and functional connectivity within resting state brain networks is not completely understood. With regard to the anatomical correlate of pain sensitivity, differences in grey matter may reflect neural processes contributing to the construction and modulation of pain in healthy individuals. As such, studies are inconsistent regarding this issue, showing positive [7] or inverse connections [6] between pain sensitivity and brain morphology. The inconsistency regarding this issue warrant further investigation which may elucidate the relationship between differences in pain sensitivity and regional grey matter and may provide novel insights into brain mechanisms contributing to that topic. Understanding brain morphology and connectivity within specific regions associated with pain processing can provide reliable anchor for the individual differences in pain response. A widely used approach to examine brain morphology from MRI images is voxel based morphometry (VBM). VBM tests for statistically significant differences in regional gray matter (GM) density between study groups, and its temporal changes. Diffusion tensor imaging (DTI) is a type of diffusion weighted imaging with the advantage of being able to resolve individual functional tracts within the white matter (WM) thus, DTI parameters serve as indirect measures of structural connectivity via the degree of integrity of WM tracts.
An online survey is conducted on MTurk populations from India and USA. Participants were assigned either a condition with primes of individualism or one with primes of collectivism, before responding to a scale on culture and indicating details of their demographics.
Within-subject, double-blind, placebo-controlled examination of opioid abuse potential in healthy individuals as a function of A118G SNP on the OPRM1 gene.
